(M5) as Fig. 6, (M6) and Fig. 7 (M7), (M8) shown in, according to the tool data DAT that is stored in the instrument file 7, make each blade 22 of same

composite tool

21,23,25,26 rotate in a circumferential direction along instrument axle center CT3, make and add optionally calibration location of the blade that uses man-hour, meanwhile, make blade platform on B shaft angle degree direction, suitably rotate the location, with each

blade

22,23,25, the 26 pairs of workpiece 17 carry out the external diameter fine finishining shown in Fig. 6 (M5), external diameter groove processing shown in Fig. 6 (M6), internal diameter whorl processing shown in Fig. 7 (M7), various processing such as outer-diameter threads processing shown in Fig. 7 (M8).In Fig. 6 and Fig. 7, the imaginary instrument 1.～7. shown in Fig. 3 (c) is not used in a part of processing, and still, also will process with the imaginary instrument that setting is stored in the composite tool 21 of the relevant Fig. 4 in the other parts of instrument file 7 this moment.For example, the imaginary instrument that uses in the external diameter fine finishining shown in Fig. 6 (M5) is exactly in the instrument file 7, instrument code name TNo is 1 (expression composite tool 21), implementation name NA is " GNLOUT ", suffix DC is " K ", calibration code name KD is " 2 ", and B shaft angle degree is the instrument of " 5 ° ", with blade 26 processing.

Thereby, after the turning process finishing that workpiece 17 is carried out, then carry out (M9), (M10) of Fig. 8 and (M11) shown in Milling Process, also to use this moment set in the instrument file 7 of composite tool 21 about boring of the 6. milling in the imaginary instrument of

composite tool

21 and 7. vertical milling, to workpiece 17 carry out the face processing of (M9), the boring processing and the base (M11) of (M10) hollows out processing.Shown in Fig. 3 (c), 6. milling in imaginary instrument boring and 7. vertical milling can to utilize any one calibration code name be that 1 blade 22 carries out Milling Process.At this moment, blade platform 20 is rotated to arrow G, H direction corresponding to processing content, changes B shaft angle degree, with the axle center CT3 location of composite tool 21, thereby by changing the center of workpiece 17, promptly changes the attitude of composite tool 21 with respect to the inclined angle alpha of Z axle.So making composite tool 21 is center when rotating at a high speed with axle center CT2, Yi Bian make the workpiece 17 that remains on the main shaft fixedly remain on the Z axle periphery and the rotation of control C axle, Yi Bian carry out Milling Process.

At this moment, in the blade of installing on the composite tool 21, instrument axle center CT3 with the blade 22 that uses in the Milling Process among Fig. 4 is the center, make the shape and the installment state of the blade 25 that is positioned at 180 ° of opposition sides identical with blade 22, shown in Figure 10 (b), beyond blade 22, blade 25 also can be used for Milling Process.At this moment, the quantity that is used for the blade of processing work is compared when having only blade 22, is at that time 2 times, can carry out milling/usefulness milling cutter fraising processing efficiently.

According to aforesaid processing, can close instrument 21 from pole machining workpiece for example shown in Figure 2 with an abdomen.

Because composite tool 21 can be equipped with a plurality of blades, can various blades be installed corresponding to processing content.Each blade carries out turning processing and milling/usefulness milling cutter fraising processing etc., at this moment, selects a blade for use in a plurality of blades of composite tool 21, beyond described processing such as Fig. 6, can certainly use a plurality of blades to carry out milling/usefulness milling cutter fraising processing simultaneously.

For example, shown in Figure 10 (a), during the periphery of turner 17,4 (the blade number that can install on the composite tool 21 is not limited to 4, here for convenience of explanation, be that example describes with the composite tool 21 that has 90 ° of spacings of being separated by with same 4 blades of Fig. 4.And Figure 10 illustrate 2

blades

29,30 that differ 180 ° of phase differences are each other only arranged) in the blade, for example, carry out turning processing with the periphery of 30 pairs of workpiece 17 of blade, shown in Figure 10 (b),

use

29,30 pairs of workpiece of blade to carry out milling/usefulness milling cutter fraising processing simultaneously.

And then, by suitably selecting to be contained in the shape of the blade on the composite tool 21 and being installed to state on its main body 21a, can certainly use the blade more than 3, carry out the milling shown in Figure 10 (b)/usefulness milling cutter fraising processing again, again by making composite tool 21 rotate the processing of holing.

Owing to use the more than one blade in such composite tool 21 to carry out multiple processing usually, so tool data management portion 8 manages the service life of each composite tool 21 as described below.

That is, as shown in Figure 9, tool data management portion 8 is stored in the management document LCF in service life of each blade of relevant each composite tool 21 in the instrument file 7, be stored together with as shown in Figure 3 tool data TL, or as its part.

blades

22,23,25,26 are housed in the composite tool 21 of Fig. 4, in order to represent their installation site, shown in Fig. 3 (a), 4 calibration code names are that the axle center CT3 with instrument is the center, turn clockwise to divide.Therefore, each

blade

22,23,25,26 and calibration code name KD are one to one.Except calibration code name KD, can certainly use any symbol that to discern each blade etc.

In service life management document LCF, with the distinguished symbol of each blade, promptly calibration code name KD has preestablished each blade regulation time in service life LF separately accordingly as service life.The operator can import this regulation time in service life LF by keyboard 5 in advance in when beginning processing, also can be by the tool presets chamber that is provided with separately beyond the compound processing machinery 1 etc. with its online writing among the management document LCF in service life.Carry out the multiple man-hour that adds with 21 pairs of same workpiece of these composite tools, also can stipulate time in service life LF, but will be set at the number in service life, as the service life of composite tool 21 with the number of the machinable workpiece of this blade.At this moment, key element process time that adds up in order to judge service life is not UT service time of blade, but the workpiece quantity of processing.When be T1 the process time of 1 workpiece, regulation time in the service life LF of blade was divided by time T 1, and this life-span number LN adopts the value of casting out its remainder.Thus, the workpiece of processing regulation number needs only the workpiece number with this blade processing, promptly uses number UN to reach number LN in service life, even the service life of this blade also had better not be with the blade processing work that reaches service life also in regulation time in service life LF.

And, the procedure that 8 simulations of tool data management portion will be carried out, for example, shown in Figure 10 (a), if judge in the composite tool 21, when only using 1 blade processing stipulated time TI, no matter this processing is turning processing, be milling/usefulness milling cutter fraising processing, still boring processing, the service time that all will be accumulated in this blade this stipulated time, UT service time of this blade was corresponding to the instrument code name TN's of this composite tool 21 among the UT, service life management document LCF, UT service time that stores in the address of this calibration code name KD that adds the blade that uses man-hour is installed.For example, carry out the man-hour that adds as Figure 10 (a), with stipulated time TI be accumulated in blade 30 corresponding calibration code name KD be among 1 address pairing service time of the UT.

Thus, when the service time of this blade, UT surpassed in advance regulation time in service life LF for this blade setting, tool data management portion 8 gives a warning, and this blade of informing this composite tool 21 of operator arrives the service life in the processing, and indication is used the preparation instrument or changed blade.Thereby, because operator's at least one blade in the composite tool 21 of reality arrived before the service life of processing work, before with this blade processing work, just known the service life of this blade, therefore, just needn't be in workpiece process, interrupt processing service life owing to composite tool 21 arrives, carry out that replacing instrument etc. is complicated, the operation of poor efficiency.

And when coming the service life of managing blade by the processing number, every with 1 workpiece of blade processing corresponding in the composite tool 21, tool data management portion 8 will with service life management document LCF, add up 1 with use number UN in the address of the corresponding calibration code name of this blade KD, when this uses number UN arrival number LN in service life, arrived service life with aforementioned this blade of this composite tool 21 of operator of similarly informing, indication is used the preparation instrument or is changed blade.At this moment, owing to, therefore, just illustrate that as previously mentioned the life-span of this blade also maintained in the time in service life as long as use number UN to be not equal to number LN in service life by processing the service life that number is come managing blade.

In addition, the procedure that 8 simulations of tool data management portion will be carried out, shown in Figure 10 (b), if judge in the composite tool 21, use the blade 29 more than 2 or 2 simultaneously, during 30 processing stipulated time TI, no matter this processing is milling/usefulness milling cutter fraising processing, still boring processing, all to will should stipulated time TI be accumulated in the service time of this blade respectively among the UT, UT service time of this blade is corresponding to the instrument code name TN's of this composite tool 21, service life management document LCF, UT service time that stores in the address of this calibration code name KD (for example, calibration code name KD is 1 and 3) that adds the blade that uses man-hour is installed.For example, carry out the man-hour that adds as Figure 10 (b), with stipulated time TI be accumulated in respectively with blade 29, the 30 corresponding calibration code name KD that use simultaneously be on 1 and 3 address pairing service time of the UT.

Thus, when the service time of any one blade in these blades, UT surpassed in advance regulation time in service life LF for this blade setting, tool data management portion 8 judges that this composite tool 21 arrives service life, and give a warning, informing has one or more blade to arrive service life in the processing in the blade of this composite tool 21 of operator, indication is used the preparation instrument to replace this composite tool 21 or changed the predetermined blade that arrives service life.Thereby, because before the service life in the actual arrival of operator's at least one blade in the composite tool 21 processing work process, before processing work, just known the service life of this blade, therefore, just needn't be in workpiece process, interrupt processing service life owing to composite tool 21 arrives, carry out that replacing instrument etc. is complicated, the operation of poor efficiency.

And, when using a plurality of blades to add man-hour simultaneously, to be added to these service times of processing employed blade process time respectively on the UT, since the service life of each blade of accumulative total, the service life that therefore can irrespectively, correctly manage each blade that constitutes composite tool 21 with the processing content that carries out with this composite tool 21.

Use a plurality of blades to add man-hour, when being undertaken managing service life by the processing number, also with foregoing the same, respectively with composite tool 21 in add the processing number on the use number of the corresponding calibration code name of the blade KD that uses, as long as the use number UN that has the process of a blade to add up in this composite tool 21 arrives number LN in its service life, from this constantly, arrived the service life of promptly judging this composite tool 21.

Utilize such tool data management portion 8, if in case judge the service life be installed at least one blade on certain composite tool 21 and arrived, will with should service life to composite tool 21 be replaced by the composite tool 21 of preparation, continue processing.

The composite tool 21 that arrives service life is transported to tool presets chamber etc. locates, this blade that reaches service life is changed to a new blade, add and reuse man-hour.Thus, be installed in a plurality of blades work in-process use effectively on the composite tool 21, till each blade arrives its service life.Therefore, can prevent from just to have arrived the discarded generation that is installed in this situation of whole blades on this composite tool 21 service life of judging composite tool no matter also have the no show blade existence in service life with preventing trouble before it happens.
